Overview
The AD780BRZ-REEL is a high precision band gap voltage reference providing pin-programmable 2.5 V or 3.0 V outputs from an input range of 4.0 V to 36 V. It features ultralow drift of 3 ppm/°C maximum and high accuracy with ±1 mV maximum error. The device operates in series or shunt mode, sourcing or sinking up to 10 mA, and includes a temperature output pin for transducer applications. It requires only a 1 µF bypass capacitor for stability.
Feature Summary
- Pin programmable selection between 2.5 V and 3.0 V output voltages
- Ultralow drift and high accuracy achieved through laser trimming
- Capable of series or shunt mode operation for positive or negative references
- Integrated temperature output pin for system monitoring
Applications
- High resolution analog-to-digital converters (ADCs)
- Digital-to-analog converters (DACs)
- Precision general-purpose reference applications
- Temperature transducer circuits
Procurement Notes
Verify the specific reel quantity against the ordering guide, as suffixes like REEL and REEL7 indicate different packing quantities. Confirm RoHS compliance status via the Z suffix. Ensure the package type matches the design footprint requirements before finalizing procurement.
Selection Notes
Select this component when low drift and high accuracy are critical for system performance. The B grade offers superior specifications compared to A or C grades. Consider the shunt mode capability if negative voltage generation without external components is required.
Part Context
This part belongs to the AD780 family of ultrahigh precision band gap references. It serves as a pin-compatible upgrade for legacy parts like the LT1019 and AD680. The BRZ variant specifically denotes the SOIC package with RoHS compliance, designed for surface mount assembly.
Replacement Considerations
The AD780BRZ acts as a direct pin-compatible replacement for the LT1019(A)-2.5 and AD680. Verify that the application can accommodate the different load on the heater supply pin found in the LT1019.
